Nonlinear forcing of climate on mountain denudation during glaciations

Constraints on the denudation of the Southern Alps over the last glacial cycle indicate a nonlinear influence of climate on landscape evolution in glaciated areas, according to a beryllium isotope record measured from quartz in a sequence of Mediterranean turbidites.

In-phase millennial-scale glacier changes in the tropics and North Atlantic regions during the Holocene

Glaciers showed a similar evolution in Greenland, Europe, the US and the tropical Andes during the Holocene. The authors propose the Atlantic Meridional Ocean Overturning Circulation as a key driver of this trend.

Steady erosion rates in the Himalayas through late Cenozoic climatic changes

Long-term Himalayan erosion rates remained stable through the global climatic changes of the past six million years, according to the cosmogenic nuclide composition of terrestrial sediments recovered from the Bay of Bengal.

Eolian chronology reveals causal links between tectonics, climate, and erg generation

Modeling cosmogenic nuclides concentrations from Kalahari Desert Sand reveals the time of sand introduction into the landscape. This coincides with morphotectonic and climatic changes that could have triggered sand production and its impact on the environment.
